INK-BOTTLE sToPPER.

To all whom z'z may concern.'

Be it known that I, JOB W. Fos'r, a citizen ofthe United States, residing at Peabody, in the county of Marion and `State of Kansas, have invented new and useful Improvements in Ink-Bottle Stoppers, of which the following is a specication.

This invention relates to improvements in ink bottle stoppers.

An object of the invention is an improvement in ink bottle stopper and particularly to a stopper provided with automatic means for closing the same.

Another object of the invention is the provision of a stopper of the class described that will tightly seal the bottle to prevent accidental spilling of the contents, but which can be readily operated upon the insertion of the pen to feed a predetermined quantity of ink.

Another object of the invention is the provision of adjusting means whereby the amount of ink which is to be fed to the pen l can be controlled to suit the writer. ,A

Further objects of the invention will be apparent from the following description taken in connection with the accompanying drawings, in which:

Figure 1 is a vertical sectional view through the bottle showing the closing means in normal or closed position.

Fig. 2 is a similar view showing the closing means in its operated or open position.

Referring to the drawings A represents an ink bottle of the ordinary construction and B the closure thereof. The closure B is provided with an opening which is reduced and threaded at its lower end to receive the exteriorly threaded lower extremity of the cylinder 10 which is flared outwardly at the top, and provided at the lower end with an inwardly extending annular flange l1, which provides a valve seat 12. Positioned within the cylinder Vis ya cup 13 provided with an outwardly extending flared upper portion 14 which bears against the inner face of the cylinder and serves to guide the same in itsv movement. The cup 13 is provided with a plurality of Specification of Letters Patent.

Application led January 2, 1917.

Serial No. 140,271.

` openings 17 at its lower end to establish communication between the bottle and the interior of the cup when the same is moved to operated position. ASecured to the lower extremity of the cup 13 is a semi-spherical shaped valve 15 which is of larger diameter than the opening formed by the inwardly extending flange 11, and is adapted to seat against the -valve seat 1:2.v A spring 16 is interposed between' the cylinder 10 and the cup 13 tending to hold the valve in its closed and outermost position by exerting its pressure against the outwardly extending flare 14 and the inwardly extending flange 11.

In operation of the device upon the insertion ofthe pen the grip portion of the same contacts with the outwardly extending flare 14, and upon downward pressure of f the 'same the cup is movedto a lowered position unseating the valve 15 and submerging the lower portion ofthe cup in the fluid vwhereby through the medium of openings.

17, the pen is fed. f

It will be noted from the construction that the quantity of fluid to be fed to the pen may be regulated through the medium of the threads provided atthe'lower extrem- D ity of the cylinder.

From the foregoing description it will be seen that I have provided a bottle stopper of novel construction which will not only prevent accidental spilling of the contents, but will alsol serve as a gage to prevent over feeding of the pen.

I claim: v l

1. In combination with the neck of a 4bottle, of a closure therefor having an opening, a cylinder adjustably mounted within the closure provided at one end with an inwardly extending annular flange, an outwardly flared cup arranged for sliding movement within the cylinder having openings formed in the lower end thereof, a valve secured upon the lowerv end of the cup, and a coil-spring encircling the cup and confined between the inwardly extending annular flange of the cylinder and the flared end of the cup for moving the cup to 2. In combination with the neck of a botthe lower end of the cup, a valve secured tle, of a closure provided with a centrally upon the lower end of theeup, and means arranged vertical opening, a cylinder adfor moving` the cup outwardly to Cause the lo justable within the closure, and provided Valve to seat against the annular flange.
